ATX - 12" x 9.5" - is also used in this arena, mainly in the entry-level server and workstation market. ATX server boards differ from their desktop cousins in that the CPU and DIMM slots have been shuffled about to improve on airflow, particularly suitable in rackmount servers. ATX can be somewhat limited, however, if you want more gear on your serverboard, especially when incorporating more than one CPU. Hence, the need for larger form-factors...
EATX (Extended ATX) - 12" x 13" - provides additional depth to the board, to allow more slots and chips to be mounted onboard when using two processors, enabling more serious server specifications.
SSI-EEB - 12" x 13" - same size as EATX but with different mounting holes. Cases will very often be designed to fit either EATX or SSI-EEB motherboards.
SSI-MEB - 16" x 13" - Together with the proprietory Serverworks SWTX form-factor (16.3" x 13"), this form-factor is for Quad-CPU solutions. Special cases are required for these boards.
The following diagram helps get the different form factors into perspective:
